When you wake up, do you sense you've had vivid dreams? Or do you just have a blank mind and headache?

Do your teeth bite together normally? Can you breathe clearly through both sides of your nose throughout the night?

That seems to be a very directed line of questioning. Mind If I ask why you seem to think sleep deprivation is the issue? Your last 2 questions trouble me a little, as I exhibit both of those conditions, rather irregularly.

My guess is sleep apnea.

Yes, exactly; this sounds like profound cognitive dysfunction consistent with either OSA or Upper Airway Resistance Syndrome. If a skeletal abnormality is present it would manifest as a compromised bite relationship, while the more mild UARS could appear with obstruction of the nasal passages.

Worth evaluating.

This is interesting, would you recommend any specific resources to research further?

Just curious, what is it to do with breathing clearly through both sides of the nose throughout the night?
